I think I saw a perfect picture on Flickr, a flower and bubbles, lots of perfect bubbles. As a read the information under the picture (no exif available) I read Meyer Gorlitz Trioplan. Never heard of it.
I soon found out it was a vintage lens, an expensive vintage lens. I bought an alternative cheap vintage lens. The Helios 44.2, few bubbles, lots of 'swirly' bokeh
As I understood better how to catch a bokeh with the Helios, my mind was still set on bubbles. So I bought another cheap lens, a projector-lens from Meyer Görlitz. I had to glue a Fuji adapter on the back-end.
Modern lenses are quite capable of a wonderful bokeh, I found out. My 35mm really could compete. With the macroring its bokeh became an abstract oilpainting.
And then I got this wonderful lens, as a present, a radioactive present! It has this mysterious glow and deep colors. The movement of the wind camouflaged the softness of the lens at f1.4, but I think this is my most bubbly bokeh yet.
